Not that I know of. But I do know one thing for a fact as I got it from the guy at Leupold's custom shop...
If you alter a leupold in ANY way after April 1, 2006, Your Leupold warranty is gone. Peroid. Other than work done in their custom shop
I asked him if Leupold was going to offer the bost and he said "No." I asked him, "So if a 'New' company steps forward and starts to modify your scopes, your are SOL as far a warranty and support from Leupold?"
He said - "Exactly"
Hope this helps?
